My son seems to have symptoms of adrenal fatigue. We are about to send a saliva test off to Genova, but I saw a post by someone about a year ago saying that a GP could do a blood test for ACTH, aldosterone and cortisol and renin. Would this give an indication of adrenal insufficiency? (I know the short synthatin test is used for a positive diagnosis)
Our GP is lovely and I'm sure he would do the blood test for my son if we asked him, but I just want to know if it is worth asking.
